Animals (Basel) 2023; 14:11. [PMID: 38200742 PMCID: PMC10778137 DOI: 10.3390/ani14010011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/07/2023] [Accepted: 12/15/2023] [Indexed: 01/12/2024] Open
Abstract
The Booroola fecundity (FecB) mutation in the bone morphogenetic protein receptor type 1B (BMPR1B) gene increases ovulation in sheep. However, its effect on follicular maturation is not fully understood. Therefore, we collected granulosa cells (GCs) at a critical stage of follicle maturation from nine wild-type (WW), nine heterozygous FecB mutant (WB), and nine homozygous FecB mutant (BB) Small Tail Han sheep. The GCs of three ewes were selected at random from each genotype and consolidated into a single group, yielding a total of nine groups (three groups per genotype) for proteomic analysis. The tandem mass tag technique was utilized to ascertain the specific proteins linked to multiple ovulation in the various FecB genotypes. Using a general linear model, we identified 199 proteins significantly affected by the FecB mutation with the LIMMA package (p < 0.05). The differential abundance of proteins was enriched in pathways related to cholesterol metabolism, carbohydrate metabolism, amino acid biosynthesis, and glutathione metabolism. These pathways are involved in important processes for GC-regulated 'conservation' of oocyte maturation. Further, the sparse partial least-squares discriminant analysis and the Fuzzy-C-mean clustering method were combined to estimate weights and cluster differential abundance proteins according to ovulation to screen important ovulation-related proteins. Among them, ZP2 and ZP3 were found to be enriched in the cellular component catalog term "egg coat", as well as some apolipoproteins, such as APOA1, APOA2, and APOA4, enriched in several Gene Ontology terms related to cholesterol metabolism and lipoprotein transport. A higher abundance of these essential proteins for oocyte maturation was observed in BB and WB genotypes compared with WW ewes. These proteins had a high weight in the model for discriminating sheep with different FecB genotypes. These findings provide new insight that the FecB mutant in GCs improves nutrient metabolism, leading to better oocyte maturation by altering the abundance of important proteins (ZP2, ZP3, and APOA1) in favor of increased ovulation or better oocyte quality.

Abstract
BMP-1/tolloid-like proteinases (BTPs) are major players in tissue morphogenesis, growth and repair. They act by promoting the deposition of structural extracellular matrix proteins and by controlling the activity of matricellular proteins and TGF-β superfamily growth factors. They have also been implicated in several pathological conditions such as fibrosis, cancer, metabolic disorders and bone diseases. Despite this broad range of pathophysiological functions, the putative existence of a specific endogenous inhibitor capable of controlling their activities could never be confirmed. Here, we show that procollagen C-proteinase enhancer-2 (PCPE-2), a protein previously reported to bind fibrillar collagens and to promote their BTP-dependent maturation, is primarily a potent and specific inhibitor of BTPs which can counteract their proteolytic activities through direct binding. PCPE-2 therefore differs from the cognate PCPE-1 protein and extends the possibilities to fine-tune BTP activities, both in physiological conditions and in therapeutic settings.

Abstract
A fundamental question in developmental biology is how morphogens, such as bone morphogenetic protein (BMP), form precise signaling gradients to impart positional and functional identity to the cells of the early embryo. We combine rigorous mutant analyses with quantitative immunofluorescence to determine that the proteases Bmp1a and Tolloid spatially restrict the BMP antagonist Chordin in dorsoventral (DV) axial patterning of the early zebrafish gastrula. We show that maternally deposited Bmp1a plays an unexpected and non-redundant role in establishing the BMP signaling gradient, while the Bmp1a/Tolloid antagonist Sizzled is surprisingly dispensable. Combining computational modeling and in vivo analyses with an immobile Chordin construct, we demonstrate that long-range Chordin diffusion is not necessary for BMP gradient formation and DV patterning. Our data do not support a counter-gradient of Chordin and instead favor a Chordin sink, established by Bmp1a and Tolloid, as the primary mechanism that drives BMP gradient formation. The BMP morphogen generates a precise signaling gradient during axial patterning. In the zebrafish embryo, Tuazon et al. find that proteases Bmp1a/Tolloid are key to this process, preventing the long-range diffusion of the BMP antagonist, Chordin. By regionally restricting Chordin, Bmp1a/Tolloid establish the signaling sink that drives BMP gradient formation.

Abstract
Proteases are a diverse group of hydrolytic enzymes, ranging from single-domain catalytic molecules to sophisticated multi-functional macromolecules. Human proteases are divided into five mechanistic classes: aspartate, cysteine, metallo, serine and threonine proteases, based on the catalytic mechanism of hydrolysis. As a protective mechanism against uncontrolled proteolysis, proteases are often produced and secreted as inactive precursors, called zymogens, containing inhibitory N-terminal propeptides. Protease propeptide structures vary considerably in length, ranging from dipeptides and propeptides of about 10 amino acids to complex multifunctional prodomains with hundreds of residues. Interestingly, sequence analysis of the different protease domains has demonstrated that propeptide sequences present higher heterogeneity compared with their catalytic domains. Therefore, we suggest that protease inhibition targeting propeptides might be more specific and have less off-target effects than classical inhibitors. The roles of propeptides, besides keeping protease latency, include correct folding of proteases, compartmentalization, liganding, and functional modulation. Changes in the propeptide sequence, thus, have a tremendous impact on the cognate enzymes. Small modifications of the propeptide sequences modulate the activity of the enzymes, which may be useful as a therapeutic strategy. This review provides an overview of known human proteases, with a focus on the role of their propeptides. We review propeptide functions, activation mechanisms, and possible therapeutic applications.

Abstract
The transforming growth factors beta (TGFβ) are local factors produced by ovarian cells which, after binding to their receptors, regulate follicular deviation and ovulation. However, their regulation and function during corpus luteum (CL) regression has been poorly investigated. The present study evaluated the mRNA regulation of some TGFβ family ligands and their receptors in the bovine CL during induced luteolysis in vivo. On day 10 of the estrous cycle, cows received an injection of prostaglandin F2α (PGF) and luteal samples were obtained from separate groups of cows (n= 4-5 cows per time-point) at 0, 2, 12, 24 or 48 h after treatment. Since TGF beta family comprises more than 30 ligands, we focused in some candidates genes such as activin receptors (ACVR-1A, -1B, -2A, -2B) AMH, AMHR2, BMPs (BMP-1, -2, -3, -4, -6 and -7), BMP receptors (BMPR-1A, -1B and -2), inhibin subunits (INH-A, -BA, -BB) and betaglycan (TGFBR3). The mRNA levels of BMP4, BMP6 and INHBA were higher at 2 h after PGF administration (P<0.05) in comparison to 0 h. The relative mRNA abundance of BMP1, BMP2, BMP3, BMP4, BMP6, ACVR1B, INHBA and INHBB was upregulated up to 12 h post PGF (P<0.05). On the other hand, TGFBR3 mRNA that codes for a reservoir of ligands that bind to TGF-beta receptors, was lower at 48 h. In conclusion, findings from this study demonstrated that genes encoding several TGFβ family members are expressed in a time-specific manner after PGF administration.

Abstract
Growth/differentiation factor 8 (GDF8), or myostatin, negatively regulates muscle mass. GDF8 is held in a latent state through interactions with its N-terminal prodomain, much like TGF-β. Using a combination of small-angle X-ray scattering and mutagenesis, we characterized the interactions of GDF8 with its prodomain. Our results show that the prodomain:GDF8 complex can exist in a fully latent state and an activated or "triggered" state where the prodomain remains in complex with the mature domain. However, these states are not reversible, indicating the latent GDF8 is "spring-loaded." Structural analysis shows that the prodomain:GDF8 complex adopts an "open" configuration, distinct from the latency state of TGF-β and more similar to the open state of Activin A and BMP9 (nonlatent complexes). We determined that GDF8 maintains similar features for latency, including the alpha-1 helix and fastener elements, and identified a series of mutations in the prodomain of GDF8 that alleviate latency, including I56E, which does not require activation by the protease Tolloid. In vivo, active GDF8 variants were potent negative regulators of muscle mass, compared with WT GDF8. Collectively, these results help characterize the latency and activation mechanisms of GDF8.

Abstract
In the present study, we tried to determine whether bone morphogenetic protein 1 (BMP1) plays a role in ovarian follicular development and early embryo development. We systematically investigated the expression and influence of BMP1 during porcine follicle and early embryonic development. Immunohistochemistry demonstrated that the BMP1 protein is expressed in granular cells and oocytes during follicular development, from primary to pre-ovulatory follicles, including atretic follicles and the corpus luteum. The mRNA expression of BMP1 significantly increased as the porcine follicles grew. Immunofluorescence analysis indicated that BMP1 was expressed in cumulus-oocyte complexes (COCs), oocytes and porcine embryos during early in vitro culture. qPCR and western blot analysis showed that the expression of BMP1 was significantly up-regulated in mature porcine oocytes and COCs compared to immature oocytes and COCs. BMP1 is expressed in early porcine embryos, and its expression reaches a peak at the 8-cell stage. To determine the effect of BMP1 on the maturation of oocytes and the development of early embryos, various concentrations of BMP1 recombinant protein or antibody were added to the in vitro culture media, respectively. BMP1 significantly affected the porcine oocyte maturation rate, the cleavage rate and the blastocyst development rate of embryos cultured in vitro in a positive way, as well as the blastocyst cell number. In conclusion, BMP1 is expressed throughout porcine ovarian follicle development and early embryogenesis, and it promotes oocyte maturation and the developmental ability of embryos during early in vitro culture.

Abstract
BMP1/TLD-related metalloproteinases play a key role in morphogenesis via the proteolytic maturation of a number of extracellular matrix proteins and the activation of a subset of growth factors of the transforming growth factor beta superfamily. Recent data indicated that BMP1 is expressed in sheep ovarian follicles and showed a protease activity. The aim of the present study was to characterize the function of the buffalo BMP1 gene in folliculogenesis. A 3195-bp buffalo BMP1 mRNA fragment was firstly cloned and sequenced, which contained a whole 2967-bp codon sequence. The multialigned results suggested that BMP1 is highly conserved among different species both at the nucleic acid and the amino acid level. BMP1 is located in the oogonium of the fetal buffalo ovary and in the granulosa cells (GCs) and the oocytes of adult ovary from the primordial to the large antral follicles. Further study showed that BMP1 promoted cell cycle and proliferation and inhibited apoptosis in IVC GCs. Adding BMP1 recombinant protein to the culture medium of the GCs increased the expression of the key cell cycle regulators such as cyclin D1 and cyclin D2 and downregulated the expression of cell apoptosis pathway genes such as Cytochrome C, Fas, FasL, and Chop, both at the mRNA and at the protein levels. It also upregulated the expression of PAPP-A, IGF system, and VEGF, and so forth, which play important roles in the selection and dominance of growth follicles. The opposite results were observed by adding BMP1 antibody to the investigation groups. This study suggests that BMP1 regulates the proliferation and apoptosis of IVC GCs by changing the expression pattern of related genes and may potentially promote the selection and dominance of the buffalo follicles.

Abstract
When it was initially discovered in 1923, inhibin was characterized as a hypophysiotropic hormone that acts on pituitary cells to regulate pituitary hormone secretion. Ninety years later, what we know about inhibin stretches far beyond its well-established capacity to inhibit activin signaling and suppress pituitary FSH production. Inhibin is one of the major reproductive hormones involved in the regulation of folliculogenesis and steroidogenesis. Although the physiological role of inhibin as an activin antagonist in other organ systems is not as well defined as it is in the pituitary-gonadal axis, inhibin also modulates biological processes in other organs through paracrine, autocrine, and/or endocrine mechanisms. Inhibin and components of its signaling pathway are expressed in many organs. Diagnostically, inhibin is used for prenatal screening of Down syndrome as part of the quadruple test and as a biochemical marker in the assessment of ovarian reserve. In this review, we provide a comprehensive summary of our current understanding of the biological role of inhibin, its relationship with activin, its signaling mechanisms, and its potential value as a diagnostic marker for reproductive function and pregnancy-associated conditions.

Abstract
Hemidesmosomes are cell-to-matrix adhesion complexes anchoring keratinocytes to basement membranes. For the first time, we present a method to prepare a fraction from human cultured cells that are highly enriched in hemidesmosomal proteins. Using DJM-1 cells derived from human squamous cell carcinoma, accumulation of hemidesmosomes was observed when these cells were cultured for more than 10 days in a commercial serum-free medium without supplemental calcium. Electron microscopy demonstrated that numerous electron-dense adhesion structures were present along the basal cell membranes of DJM-1 cells cultured under the aforementioned conditions. After removing cellular materials using an ammonia solution, hemidesmosomal proteins and deposited extracellular matrix were collected and separated by electrophoresis. There were eight major polypeptides, which were determined to be plectin, BP230, BP180, integrin α6 and β4 subunits, and laminin-332 by immunoblotting and mass spectrometry. Therefore, we designated this preparation as a hemidesmosome-rich fraction. This fraction contained laminin-332 exclusively in its unprocessed form, which may account for the promotion of laminin deposition, and minimal amounts of Lutheran blood group protein, a nonhemidesmosomal transmembrane protein. This hemidesmosome-rich fraction would be useful not only for biological research on hemidesmosomes but also for developing a serum test for patients with blistering skin diseases.

Abstract
The liver, pancreas, and lungs are induced from endoderm progenitors by a series of dynamic growth factor signals from the mesoderm, but how the temporal-spatial activity of these signals is controlled is poorly understood. We have identified an extracellular regulatory loop required for robust bone morphogenetic protein (BMP) signaling in the Xenopus foregut. We show that BMP signaling is required to maintain foregut progenitors and induce expression of the secreted frizzled related protein Sizzled (Szl) and the extracellular metalloprotease Tolloid-like 1 (Tll1). Szl negatively regulates Tll activity to control deposition of a fibronectin (FN) matrix between the mesoderm and endoderm, which is required to maintain BMP signaling. Foregut-specific Szl depletion results in a loss of the FN matrix and failure to maintain robust pSmad1 levels, causing a loss of foregut gene expression and organ agenesis. These results have implications for BMP signaling in diverse contexts and the differentiation of foregut tissue from stem cells.

Abstract
BMP-1/tolloid-like proteinases (BTPs) are major enzymes involved in extracellular matrix assembly and activation of bioactive molecules, both growth factors and anti-angiogenic molecules. Although the control of BTP activity by several enhancing molecules is well established, the possibility that regulation also occurs through endogenous inhibitors is still debated. Secreted frizzled-related proteins (sFRPs) have been studied as possible candidates, with highly contradictory results, after the demonstration that sizzled, a sFRP found in Xenopus and zebrafish, was a potent inhibitor of Xenopus and zebrafish tolloid-like proteases. In this study, we demonstrate that mammalian sFRP-1, -2, and -4 do not modify human BMP-1 activity on several of its known substrates including procollagen I, procollagen III, pN-collagen V, and prolysyl oxidase. In contrast, Xenopus sizzled appears as a tight binding inhibitor of human BMP-1, with a K(i) of 1.5 ± 0.5 nM, and is shown to strongly inhibit other human tolloid isoforms mTLD and mTLL-1. Because sizzled is the most potent inhibitor of human tolloid-like proteinases known to date, we have studied its mechanism of action in detail and shown that the frizzled domain of sizzled is both necessary and sufficient for inhibitory activity and that it acts directly on the catalytic domain of BMP-1. Residues in sizzled required for inhibition include Asp-92, which is shared by sFRP-1 and -2, and also Phe-94, Ser-43, and Glu-44, which are specific to sizzled, thereby providing a rational basis for the absence of inhibitory activity of human sFRPs.

Abstract
Many secreted proteins are synthesized as precursors with propeptides that must be cleaved to yield the mature functional form of the molecule. In addition, various growth factors occur in extracellular latent complexes with protein antagonists and are activated upon cleavage of such antagonists. Research in the separate fields of embryonic patterning and extracellular matrix formation has identified members of the BMP1/Tolloid-like family of metalloproteinases as key players in these types of biosynthetic processing events in species ranging from Drosophila to humans.

Abstract
Bone morphogenetic proteins (BMPs) participate in organ regeneration through autocrine and paracrine actions, but the existence and effects of these proteins in the systemic circulation is unknown. Using liquid chromatography-mass spectrometry, we identified BMP6, GDF15, and the BMP1-3 isoform of the Bmp1 gene in plasma samples from healthy volunteers and patients with CKD. We isolated the endogenous BMP1-3 protein and demonstrated that it circulates as an active enzyme, evidenced by its ability to cleave dentin matrix protein-1 in vitro. In rats with CKD, administration of recombinant BMP1-3 increased renal fibrosis and reduced survival. In contrast, administration of a BMP1-3-neutralizing antibody reduced renal fibrosis, preserved renal function, and increased survival. In addition, treating with the neutralizing antibody was associated with low plasma levels of TGFβ1 and connective tissue growth factor. In HEK293 cells and remnant kidneys, BMP1-3 increased the transcription of collagen type I, TGFβ1, β-catenin, and BMP7 via a BMP- and Wnt-independent mechanism that involved signaling through an integrin β1 subunit. The profibrotic effect of BMP1-3 may, in part, be a result of the accompanied decrease in decorin (DCN) expression. Taken together, inhibition of circulating BMP1-3 reduces renal fibrosis, suggesting that this pathway may be a therapeutic target for CKD.

Abstract
Members of the astacin family of metalloproteinases such as human bone morphogenetic protein 1 (BMP-1) regulate morphogenesis by processing precursors to mature functional extracellular matrix (ECM) proteins and several growth factors including TGFβ, BMP2, BMP4 and GFD8. We have recently discovered that BMP1-3 isoform of the Bmp-1 gene circulates in the human plasma and is significantly increased in patients with acute bone fracture. We hypothesized that circulating BMP1-3 might have an important role in bone repair and serve as a novel bone biomarker. When administered systemically to rats with a long bone fracture and locally to rabbits with a critical size defect of the ulna, recombinant human BMP1-3 enhanced bone healing. In contrast, neutralization of the endogenous BMP1-3 by a specific polyclonal antibody delayed the bone union. Invitro BMP1-3 increased the expression of collagen type I and osteocalcin in MC3T3-E(1) osteoblast like cells, and enhanced the formation of mineralized bone nodules from bone marrow mesenchymal stem cells. We suggest that BMP1-3 is a novel systemic regulator of bone repair.

Abstract
Periprosthetic osteolysis of joint replacements caused by wear debris is a significant complication of joint replacements. Polymethylmethacrylate (PMMA) particles have been shown to inhibit osteogenic differentiation, but the molecular mechanism has not been previously determined. In this study, we exposed differentiating MC3T3-E1 preostoblast cells to PMMA particles and determined the changes that occurred with respect to p38 mitogen-activated protein kinase (MAPK) activity and the transforming growth factor (TGF)-beta1 and bone morphogenetic protein (BMP) signaling pathways. In the absence of particles, MC3T3-E1 cells demonstrate activation of p38 MAPK on day 8 of differentiation; however, when treated with PMMA particles, differentiating MC3T3-E1 cells demonstrate the suppression of p38 activity on day 8 and show activation of p38 on days 1 and 4. On day 4 of particle exposure, the differentiating MC3T3-E1 cells show significant downregulation of TGF-beta1 expression, which is involved in osteoblast differentiation, and a significant upregulation of the expression of BMP3 and Sclerostin (SOST), which are negative regulators of osteoblast differentiation. By day 8 of particle exposure, the changes in TGF-beta1, BMP3, and SOST expression are opposite of those seen on day 4. This study has demonstrated the distinct changes in the molecular profile of MC3T3-E1 cells during particle-induced inhibition of osteoblast differentiation. (c) 2010 Wiley Periodicals, Inc.

Abstract
Bone morphogenetic protein (BMP) 1 is a vertebrate metalloproteinase of the astacin family. BMP1 plays a key role in regulating the formation of the extracellular matrix (ECM), particularly by processing the C-propeptide of fibrillar procollagens. BMP1 also promotes BMP signaling by releasing BMP signaling molecules from complexes with the BMP-antagonist chordin. As a result of BMP1's dual role in both ECM formation and BMP signaling, we hypothesized that BMP1 could play a role in ovarian physiology. Using the sheep ovary as a model system, we showed that BMP1 was expressed in the ovary throughout early fetal stages to adulthood. Furthermore, in adult ovaries, BMP1 was expressed along with chordin, BMP4, and twisted gastrulation, which together form an extracellular regulatory complex for BMP signaling. Within ovine ovaries, immunohistochemical localization demonstrated that BMP1 was present in granulosa cells at all stages of follicular development, from primordial to large antral follicles, and that the levels of BMP1 were not affected by the final follicle selection mechanism. In cultured granulosa cells, BMP1 expression was not affected by gonadotropins, but BMP4 and activin A had opposing effects on the levels of BMP1 mRNA. BMP1 appeared to be secreted into the follicular fluid of antral follicles, where it is able to exert procollagen C-proteinase and chordinase activities. Interestingly, BMP1 activity in follicular fluid decreased with follicular growth.

Abstract
In Xenopus embryos, a dorsal-ventral patterning gradient is generated by diffusing Chordin/bone morphogenetic protein (BMP) complexes cleaved by BMP1/Tolloid metalloproteinases in the ventral side. We developed a new BMP1/Tolloid assay using a fluorogenic Chordin peptide substrate and identified an unexpected negative feedback loop for BMP4, in which BMP4 inhibits Tolloid enzyme activity noncompetitively. BMP4 binds directly to the CUB (Complement 1r/s, Uegf [a sea urchin embryonic protein] and BMP1) domains of BMP1 and Drosophila Tolloid with high affinity. Binding to CUB domains inhibits BMP4 signaling. These findings provide a molecular explanation for a long-standing genetical puzzle in which antimorphic Drosophila tolloid mutant alleles displayed anti-BMP effects. The extensive Drosophila genetics available supports the relevance of the interaction described here at endogenous physiological levels. Many extracellular proteins contain CUB domains; the binding of CUB domains to BMP4 suggests a possible general function in binding transforming growth factor-beta (TGF-beta) superfamily members. Mathematical modeling indicates that feedback inhibition by BMP ligands acts on the ventral side, while on the dorsal side the main regulator of BMP1/Tolloid enzymatic activity is the binding to its substrate, Chordin.

Abstract
The presence of calcification is the most significant ultrasonographic finding in evaluating thyroid nodules. Calcifications are more frequently detected in papillary thyroid carcinoma than in other thyroid lesions. However, the clinical significance of calcification, including clinical correlations and impact on survival, and the molecular mechanism responsible for calcification in papillary thyroid carcinoma remain uncertain. We performed a retrospective study of patients with primary common-type papillary thyroid carcinoma to determine the clinical correlations of calcification and its impact on survival. Histologically, calcification was classified as either psammoma bodies, stromal calcification, or bone formation. They were identified in 25, 47, and 13% of all 229 cases of papillary thyroid carcinoma, respectively. The presence of psammoma bodies was significantly correlated with gross lymph node metastasis and stage grouping. Both stromal calcification and bone formation were significantly correlated with patient age. In addition, stromal calcification was associated with pT classification and gross lymph node metastasis. Papillary thyroid carcinoma with, compared to that without, psammoma bodies was associated with poorer disease-free survival. We examined the quantitative expression of BMP-1, a metalloproteinase that is reported to be involved in bone and extracellular matrix formations, and found that its expression was significantly higher in tumors with psammoma bodies or with stromal calcification (P=0.0464 and 0.0272, respectively). These results suggest that the presence of psammoma bodies is a useful predictor of outcome for patients suffering from papillary thyroid carcinoma.

Abstract
Emerging evidence has revealed an endocrine function for skeletal muscle; in fact, certain anti-inflammatory cytokines are secreted only from contractile skeletal muscle. However, the skeletal muscle secretome as a whole is poorly characterized, as is how it changes in response to extracellular stimuli. Herein, we sought to identify and characterize the members of the skeletal muscle secretome, and to determine which protein secretion levels were modulated in response to insulin stimulation. To conduct these studies, we treated differentiated L6 rat skeletal muscle cells with insulin or left them untreated, and we comparatively analyzed the proteins secreted into the media. We fractionated this conditioned media using offline RP HPLC, digested the fractionated proteins, and analyzed the resulting peptides with LC-ESI-MS/MS. We identified a total of 254 proteins, and by using three different filtering methods, we identified 153 of these as secretory proteins. Fourteen proteins were secreted at higher levels under insulin stimulation, including several proteins known to be highly secreted in metabolic diseases; 19 proteins were secreted at lower levels under insulin stimulation. These result not only pinpointed several previously unknown, insulin induced, secretory proteins of skeletal muscle, it also described a novel approach for conditioned secretome analysis.

Abstract
Trout normally spawn at 3 years of age, however, a small percentage mature a year early. This provides an opportunity to study reproductive timing and developmental processes. The ovarian and testicular extracellular matrix (ECM) participates in processes such as growth, adhesion, differentiation, cell migration and patterning. The composition of the ECM defines the interactions of specific regulatory ligands with their receptors and modulates and regulates gonadal function. To identify some of the genes involved in these processes, a 16,006-gene salmonid cDNA microarray was used to compare three-year-old normal with two-year-old normal (maturing) and with two-year-old precocious (pre-spawn) ovarian and testicular transcriptomes. We provide evidence for differences in expression of some of the genes during vasculogenesis, angiogenesis, fibrillogenesis and other processes involving ECM remodeling. Sex-specific gene expression differences of ECM components were documented between the trout ovary and testis in each developmental state. Significant differences in the expression of genes involved in translation, transcription, cell-cycling and differentiation were identified. We also report, for the first time, unequivocal evidence for the transcription of high levels of adult and embryonic hemoglobins in the developed ovary; and for the expression of transcripts that encode zona pellucida glycoproteins in both the ovary and testis of trout.

Abstract
The bisphosphonate class of antiresorptive drugs and active forms of parathyroid hormone (PTH (1-34)) have been used clinically to enhance bone mass and density in patients with osteoporosis. Abundant evidence suggests that the mechanism by which PTH (1-34) increases bone density is stimulation of osteoblast differentiation. Although bisphosphonates have been classically thought to increase bone density by inhibiting osteoclasts, there is increasing evidence to suggest that bisphosphonates have direct stimulatory effects on osteoblast differentiation. Interestingly, in patients with osteoporosis, combination therapy with bisphosphonates and PTH (1-34) is not synergistic in increasing bone density; bisphosphonates appear to blunt the effect of PTH (1-34). To begin to understand the mechanism governing the effects of these agents on osteoblasts and a possible explanation for their apparent antagonism, we examined the expression of several bone morphogenetic proteins (BMPs) in MC3T3-E1 preosteoblastic cells either untreated, or treated with alendronate, parathyroid hormone, or a combination of the two agents. We find by reverse transcriptase-polymerase chain reaction (RT-PCR) that while alendronate fails to induce the expression of any of the BMPs tested, several BMPs are induced by PTH (1-34). The induction of the PTH (1-34)-inducible BMPs is blocked with simultaneous alendronate treatment. These data suggest that alendronate interferes with PTH (1-34)-induced BMP gene transcription and provides a possible basis for the antagonism observed between the two agents in increasing bone density.

Abstract
A decade ago, bone morphogenetic protein 1 (BMP1) was shown to provide the activity necessary for proteolytic removal of the C-propeptides of procollagens I-III: precursors of the major fibrillar collagens. Subsequent studies have shown BMP1 to be the prototype of a small group of extracellular metalloproteinases that play manifold roles in regulating formation of the extracellular matrix (ECM). Soon after initial cloning of BMP1, genetic studies showed the related Drosophila proteinase Tolloid (TLD) to be necessary for the formation of the dorsal-ventral axis in early embryogenesis. It is now clear that the BMP1/TLD-like proteinases, conserved in species ranging from Drosophila to humans, act in dorsal-ventral patterning via activation of transforming growth factor beta (TGFbeta)-like proteins BMP2, BMP4 (vertebrates) and decapentaplegic (arthropods). More recently, it has become apparent that the BMP1/TLD-like proteinases are activators of a broader subset of the TGFbeta superfamily of proteins, with implications that these proteinases may be key in orchestrating the formation of ECM with growth factor activation and BMP signaling in morphogenetic processes.
